Understanding additional premium charges for surety bonds

Contractors are often surprised when additional premium charges arise in connection with a surety bond. While these costs can feel unexpected, they are usually the result of specific contractual or commercial factors rather than arbitrary pricing decisions by the surety. Understanding why additional premiums occur — and how they can often be avoided — helps contractors manage costs and maintain strong surety relationships.

An additional premium is a further charge applied by the surety after a bond has been issued. This typically arises when the bond remains in place for longer or under different circumstances than originally anticipated. These charges are governed by the bond wording and the terms agreed at inception.

The most common reason why an additional premium is charged is because of extensions to the contract duration (through variations, delays or disputes etc.). If the bonded contract runs beyond its original completion date, the surety’s exposure continues for longer, often triggering an additional premium on a per annum basis.

Sureties apply these charges as bonds are originally underwritten on a defined scope, value, and duration. When any of these element’s change, the surety is effectively providing additional credit support beyond what was originally priced. Additional premiums are therefore a reflection of increased time on risk or increased exposure — not a penalty.

The importance of early communication

Many additional premium charges can be anticipated or mitigated through early engagement. Keeping sureties informed of programme changes, extensions, or variations allows them to assess risk proactively rather than reactively. In some cases, clear explanation and supporting information can reduce or even avoid additional charges.

At DRS, we specialise in bond management and add real value by:

• Clarifying potential additional premium triggers at inception

• Reviewing bond wordings and renewal terms

• Challenging unnecessary or excessive charges

• Negotiating proportionate premiums based on actual exposure

• Helping contractors plan for bond-related costs within project budgets on a regular basis.

  
  

This oversight ensures that contractors pay only what is reasonable and appropriate for the risk being supported and limits unexpected invoices landing on desks. 

In summary, additional premium charges under bonds are not uncommon, but they should never come as a complete surprise. With the right understanding, planning, and advice, contractors can manage these costs effectively and avoid unnecessary expense.
